Renewed September 11, L935 3 Claims.

This invention has .reference to a machine .for applying a .bu'c'kle toa band or .s'trap aof :metal, and particularly for applying buckles tobands used in conjunction with cotton compresses.

The invention also :consists the provision of an improved method offolding one end of a band in a manner to positively secure the bucklethereto, as "well as the provision cof :an "efii'cient -hand machine forWorking the send of the "band.

The invention together with its objects and advantages will be :bestunderstood from a "study of the following description taken in:connection-with the accompanying =drawings wherein:

Figure 1 is an elevational view of the machine.

Figure 2 is a top plan view thereof.

Figure 3 is ;a perspective view showing the first step in applying thebuckle to the band.

Figure 4 is a similar view illustrating the next to the last step inapplying the buckle and after the folding of the band by the machine hasbeen completed.

Figure 5 is a perspective view illustrating the final step in theapplication of the buckle to the band.

Figure 6 is a perspective view of an ejector sleeve.

Figure 7 is a perspective view of the folding head and associated shaft.

Referring to the drawings by reference numerals it will be seen that themachine comprises a base or platform 5 having rising from one edgethereof a support 6 which in'the present instance extends forsubstantially the full length of the base 5. Provided on the upper edgeof the support 6 intermediate its ends is a bearing I in which isjournalled a shaft 8 equipped on one end with a hand crank 9.

On the end thereof opposite to the crank 9 the shaft 8 is provided witha head III which is provided with a series of fingers II, in the presentinstance preferably three fingers arranged in staggered relation asshown.

Slidably engaged with the shank portion of the head I is a sleeve 21provided adacent one end with a collar 28 adapted to abut the adjacentend of the bearing 1 for limiting inward movement of the sleeve 21relative to the head. At its forward end the sleeve 21 has removablysecured therein through the medium of a pin 29 an ejector element 30that is adapted to operate in a slot 3| provided therefor in the headIII.

For reciprocating the sleeve 21 there is provided a lever I8 that ispivoted at I9 to a lug projecting from the support 6, and on the underside thereof the lever I8 is equipped with spaced depending lugs 3|"that are disposed :at opposite sides of the flange '28 for engagementtherewith to project for retract the sleeve upon swinging tmovem'ent of"the 'lever I B in the proper direction.

.A curved carrier member 1.3 is pivoted to the base as at 1 4 and isprovided at its .free lend with :a .freely .joumall'ed roller 15. Tirecarrier is norinallt urged to rotate in :a clockwise direction(Figure 1) through the medium of :a coil 0 spring I- 6 that is anchored:at one end to :the base 5 as :at H and is secured :at its opposite endto the carrier t3 :as shown in Figure 11. It will thus be seen thatunder action #Of the spring 116 :the :roller 4-5 will be held inconstant contact with 1-5 'the band I-2 during rotation of the :head1:0- .in the manifolding operation.

The carrier I3 on one side thereof is provided with a lug 2| with whichis engageable a lug carried by the lever I8 upon movement of the golever I8 forwardly to project the sleeve 21. It will thus be seen thatincidental to a projection of the sleeve 21 the carrier I3 will becaused to swing in a counter-clockwise direction away from the edge I 0thus permitting of the folded portion of the band I2 being forced out ofengagement with the fingers I I of the head I 0. This latter operationis performed obviously, by upon projection of the sleeve 21, andengagement of the pin with the folded portion of the strap I2 in amanner to force said portion in the direction of the length of thefingers to become disengaged therefrom.

In using the machine the buckle I3a is first passed on to one end of theband I2 as suggested in Figure 3. The end of the band is then passedthrough the fingers II. Next the crank 9 is rotated to effect a manifoldbending of the band I2, the band first folding to provide the fold 22,then the fold 23 and finally the fold 24. When 40 this folding operationis completed the end. of the band may be folded as shown in Figure 4.Upon completion of this operation the lever I8 is swung forwardly toproject the sleeve 21 and thereby engage the member 30 carried by thesleeve with the folded portion of the band to disengage said portionfrom the head I0 in a manner hereinbefore explained. v

When the folding operation has been completed and the band disengagedfrom the head III buckle I 3a is then slid forwardly into positionbetween the bend 25 connecting the folds 22 and 23 and the bend 26connecting the fold 24 with the strap proper.

When the buckle I3a has been moved to the position just stated a secondattendant with a mallet or the like completes the folding, and when .thefolding operation is completed the folds, as shown in Figure 5 will beparallel to one another and with the strap I2 with a portion of theframe of the buckle positively secured in place and in a manner not toeasily work loose.

Having thus described my invention, what I claim as new is:

1. A hand machine for applying buckles to metallic bands comprising arotatably supported shaft, a head on the shaft provided with a series ofstaggeredly arranged fingers adapted to have an end of a band threadedtherethrough so that upon rotation of the head the manifolding of the.

band may be accomplished, and means associated with-the head fordisengaging the folded portion of the band from said head, said meansincluding a sleeve slidable on the shaft longitudinally thereof, and anejector member arranged within one end of the sleeve and operatingbetween certain fingers on the head in a manner to engage an edgeportion of the band upon projection of the sleeve forwardly with respectto the head, and means for projecting and retracting said sleeveincluding a collar on the sleeve, a pivotally mounted lever, and spacedlugs on the lever engaging the collar at opposite sides thereof fortransmitting movement of the lever to the sleeve.

2. A folding machine of the class described comprising a base, a supportrising therefrom, a shaft rotatably mounted on the support, a foldinghead on one end of the shaft, and provided with a slot, an ejectorsleeve slidably mounted on the shaft, an ejector member provided in oneend of the sleeve and arranged to operate within the slot, said sleevebeing also provided with a collar, a lever pivoted at one end to thesupport and provided intermediate its ends with lugs engaging oppositesides of the collar for transmitting movement of the lever to thesleeve, a carrier member pivoted on the base laterally of the shaft, aroller carried by the carrier member for engaging the article to befolded/during rotation of the head, and spring means engaged with thecarrier for normally urging the roller into operative position relativeto said head.

3. A folding machine of' the class described comprising a base, asupport rising therefrom, a shaft rotatably mounted on the support, afolding head on one end of the shaft, and provided with a slot, anejector sleeve slidably mounted on the shaft, an ejector member providedin one end of the sleeve and arranged to operate within the slot, saidsleeve being also provided with a collar, a lever pivotedat one end tothe support andprovided intermediate its ends with lugs engagingoppositesides of the collar for transmitting movement of the lever tothe sleeve, a carrier member pivoted on the base laterally of the shaft,a roller carried by the carrier member for engaging the article to befolded during rotation of the head, and spring means engaged with thecarrier for normally urging the roller into opera- 7 tive positionrelative to said head, said carrier being provided with a lug, and saidlever being provided with a lug for engaging the lug on the carrier toswing the latter in a direction away from the head upon movement of thelever to project said sleeve.
